GRAIN-SCOURING APPLIANCE.

Application filed April 21,1915. Serial N 0. 22,951.

To all whom it may concern." I

Be it known that I, LEVI HICKS, a citizen of the United States of America, residing at Holland, in the county of Ottawa and State of Michigan, have invented certain new and useful Improvements in Grain-scouring Appliances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to grain scouring devices, and it is the object and purpose thereof to provide improvements in the easing and grain scouring machine whereby the grain taken into the machine will be cleaned and more thoroughly scoured to remove impurities from the grain than heretofore. It is a further object and purpose of the invention to fashion the inner surface of the casing and the surfaces of the beating bars with various roughened depressions and abrasive projections respectively such that when the grain is acted upon by the bars the surface of each kernel of grain will be scoured removing any and all impurities which may have collected on the outside of the kernels. The improvements by which these ends are attained are shown in the accompanying drawings, in which;

Figure 1 is a front elevation, with the frame removed and with parts of the scourmg casing omitted, of a scouring machine to which my improvements are applied.

Fig. 2 is a front elevation of one of the curved plates, a plurality of which are used to make the scouring casing.

Fig. 3 is a perspective view of the preferred form of scouring plate.

Fig. 4 is a transverse section taken through the plate shown in Fig. 3.

Fig. 5 is a perspective view of one of the improved beating bars used; and

Fig. 6 is an enlarged fragmentary sec tional view through one ofthe depressions formed in the plate shown in Fig. 3.

Like reference characters refer to like parts throughout the several views of the drawings.

in the rotating beating bars of a A well known type of scouring machine is shown in Fig. 1 and comprises a frame 1 in which is mounted a horizontal shaft 2 adapted to be driven through the pulley 3 attached at one end thereof. Adjacent its opposite end a fan 4 is secured to the shaft and rotates in the fan box 5 shown, which box is directly connected with the scouring casing .6 supported in the frame between i the fan in the drive pulley.

plate 9, passing into an outlet spout 12 as shown in Fig.

-1. Each of the curved plates 7 is provided with lugs 13 for attachment to similar lugs on adjacent plates to form the cylindrical casing, bolts 14 extending through these lugs to secure the plates together. All of the plates are provided with a large number of transverse slots 15 as shown. I

Scouring machines of the construction thus r described are old and well known. y improvement in the casing construction consists informing a plurality of depressions'on the inner surfaces of the plates 7 as shown at 16, which are roughened slightly so that as the grain is thrown against the surfaces a slight abrasive action against the outer surface of the kernels of the grain takes place, rubbing or scouring off any dirt, smut or like impurities that may be on the outer surface of the grain and more completely scouring it than heretofore. Instead of the depression 16 it may be advisable to make a plurality of elongated depressions or flutes as shown at 17 in Fig. 2. It will, however, be noted that in both cases the depressions have angular surfaces, substantially against which the grain will be thrown so that it will be'naturally turned back again after it is thrown into the depressions, whether of the form shown in Fig. 3 or that shown in Fig. 2. Other vmodifications may be resorted to. For instance,'the location of the depressions or flutes 17 need not .be parallel to the a length of the plate 7 but may lie at any deslots 21 adjacent the ends of the bars. These bars lie parallel to the length of the scour ing casing with their outer edges spaced 'a short distance from the inner surface of the casing, On each edge the bar is formed with a plurality of ribs 22 while both sides of the bar have a plurality of projections 23 extending outwardly therefrom. It will be noted that the barf) has the appearance of a raspand as a matter of practice an ordinary rasp may be used with good results as the beating bar in the embodiment of my inthe depression,

vention. Heretofore these bars have been plain but my improvement in the bar consists in the roughening of the sides and edges of the bar to form projections and surfaces that will operate with considerable severity on the outer surface of the kernels of the grain. It has been found in practical ex perience that the projections 23 on the bar will even enter the creases in the kernels of grain such as wheat or rye, and remove any dirt that may have become fixed therein.

With a construction as thus described the advantages will be readily apparent. Grain entering through the entrance 10 is acted 'upon by the bars 20 which are rotated Very rapidly, sometimes at the rate of seven hundred revolutions per minute. The rotation has the effect of throwing the grain outwardly against :the inner surface of the scouring casing ,and as the grain passes across the'face of the beating bar it is rasped andsc'oured by the rough surface thereof as will be readily apparent. As it leaves the beating bar and is thrown against the inner surface of the casing it is carried into a depression 16 or'17 and is'further scoured as it strikes against the roughenedsurfaces in being again turned outwardly by reason of the incline at which these surfaces are cut so as to come in contact again with the beating bar. Also the edges 22of the bars act against grain which may be-between the bars and the casing.

The fan serves to draw airthrough'the slots 15 and through the passageway into the fan casing. A large amount of the lighter impurities in the form of dust in this manner are carried out of the scourin casing and are discharged by the fan, whi e the heavier scourings pass through the slots 15 and are dFischarged through the funnel 24 shown in These improvements in scouring machines make itpossible to clean and place in condition for milling, grain which heretofore has been practically useless for milling purposes. The abrasive action of the beating bars in connection with the scouring action of the roughened surfaces of the depressions cleans the kernels of grain much better and more satisfactorily than heretofore. Grain entering the scouring casing in a dirty and foul condition is discharged through the outlet 12 in a perfectly clean and bright condition ready for milling purposes.

Slight modifications in detail may be resorted to without departing from my invention which is defined in the" appended claims and all modifications in construction falling within the scope of said claims are to be considered as comprehended within my invention.

I claim i 1. In a grain scouring machine, a scouring casing. having a plurality of depressions the sides of which are roughened and lie at an angle to the inner surface of the casing, a shaft extending through the casing, arms projecting radially from the shaft, and beating bars secured at the ends of the arms, said bars being comparatively wide and thin, having sides and edges formed with abrading projections and positioned so that the width of a bar is at right angles to the inner surface of the casing, substantially as described.-

' 2. In a grain scouring machine, a scouring casing having a plurality of depressions formed on its inner surface, the surfaces at the depressions being roughened, comparatively wide and thin, beating bars positioned lengthwise of the casing and adjacent the inner surface thereof and extending inwardly therefrom, and abrading projections formed on the sides and edges of said bars, said projections on the side being located diagonally across the surface of said sides, substantially as described.

3. In a grain scouring machine, a scouring casing having a plurality of conical depressions formed on the inner surface thereof, thesurfaces at the depressions being roughened, a plurality of comparatively wide and thin.' beating bars, each having abrading projections on the sides and edges thereof, positioned lengthwise of the casing and adjacent the inner surface thereof, the edges of said bars being located directly opposite the an obtuse angle to the inner surface of the 10 inner surface of the casing and the sides of easing, substantially as described. the bars at right angles thereto, and means In testimony whereof I affix my signature to rotate said bars, substantially as dein presence of tWo Witnesses. 5 scribed.
